windows undoes changes after it updates

Anonymous

So my system is a windows 10 home 22h2 and every time it tries to update, it lasts 2 or more hours updating then when it finishes it says "undoing changes made to your computer" in a black screen and then when I go to windows update page to see what happened they give me this error code: 0xc1900101

What i've tried already: doing sfc/scannow, disabling windows firewall (I don't have any other antivirus), I tried running setupdiag.exe with the prompts however somehow it does not create any log file so I can't see what went wrong (maybe I don't used it correctly). I searched the meaning of the error code it gave me and it said there's an incompatible driver.

I recently changed my motherboard and my processor, does it have anything to do with it?? Should I try to update my pc using these parts again? I still have them. My old processor was a i5 4440 3.10 Ghz and my new one is a i5-4590 3.30Ghz and my two motherboards are not from "mainstream" brands like Asus or Gigabyte but they're not the same brands.

Also, another little detail I need to mention is when the update finished the file setupdiag.exe appeared out of nowhere in my downloads folder but it still did not created any log file. Help!!! it's the fourth time the system tries to update but no success!!!

Thanks. Now, please run these commands.

Download CBSDiag.bat from the GitHub page below:

https://gist.github.com/winhelponline/819c9abe3...

Right-click cbsdiag.bat, click Properties, select Unblock, and click OK.

Right-click cbsdiag.bat, and choose "Run as administrator".

(The batch file contains plain text code. You can read its contents using Notepad before running it. It collects the CBS registry key and servicing-related information to fix the corruption.)

The batch file creates a file named CBSDiag.zip on your desktop. Share the file on OneDrive.

so, the media creation thing you sent me is telling me "install windows 10 home" and "keep app and personal files", now i'm confused, i already have windows 10 home so it wants to install it again or it just wants to update the windows 10 home i already have? (by the way, before it told me to "install windows 10 home" it loaded for a while)
